When the unit pulses, you should be able to hear the pulse of oxygen and see the LED turn off
momentarily. Allow Focus to run for 5 minutes before recording the oxygen concentration of the
unit.
5.4. With a short length of tubing 12 in. (30 cm), connect a calibrated
Teledyne Analytical Instruments oxygen analyzer (Model AX-300)
or Fujikura Oxygen Analyzer (Model FCX-HOM or FCX-OM3).
to the oxygen outlet on the Focus concentrator. Turn on the
analyzer and record the unit’s concentration. The concentration
specification in test mode is 87% or greater.
6.0 Routine Maintenance Instruction for Patient
To ensure accurate output and efficient operation of the unit, the patient must contact the
Equipment Provider for inspection/service when the alarm/service indicator illuminates.
6.1 Alarm/Service Indicator
The Focus unit should be serviced after every 5,000 hours of use. This should include replacing
the compressor felt filter, a check of oxygen concentration, etc. When the unit has reached 5,000
hours of use, an amber LED will illuminate on the right side of the unit’s control panel. Instruct
patients to notify the Equipment Provider when this happens.
If the oxygen concentration of the unit is below 87%, the system’s operating pressure should
be measured to verify the compressor is functioning within specification. If the system pressure
is below 19 psig (131 kPa), make sure that the unit is leak-free by testing all tubing connections
and fittings with leak-testing solution. If no leaks are present, replace the compressor.
AirSep does not recommend the sterilization of this equipment.
7.0 Equipment Provider Maintenance
7.1 Equipment Provider Routine Maintenance
The Focus unit includes one filter and a compressor that require scheduled maintenance
or replacement.
To ensure that the output of oxygen is within specification, you must perform an oxygen
concentration test. (Refer to Section 5, “Oxygen Concentration Test and Specification,” of this
manual.) Test the unit upon delivery to a patient and at periodic intervals. Equipment
Providers, based on their expertise and documentation, may establish and implement their own
protocol to check oxygen concentration. The interval established may be longer or shorter than
90 days, AirSep’s default time period for providers who do not choose to establish their
own protocol.
7.2 Compressor Servicing
As the Equipment Provider, you are responsible for monitoring the life of the compressor, which
must be checked at every 5,000 hours of use.
